  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • The aim of this article is to discuss challenges in the development of Specialist Nursing Educations as a result of the 2007 Swedish Higher EducationReform: the implementation of the so-called Bologna process. Certain challenges follow this reform, particularly since the specialist nursingprogrammes will be part of the second cycle of the higher education system, and it will be possible to combine the professional degree witha masters degree (one year). Possible strategies in four areas related to the Specialist Nursing Education are discussed: integration of researchbasedknowledge, experienced-based knowledge, improvement knowledge, and strategies for collaboration between university institutions andclinics. Specific didactical issues are raised.

  • One-Year Survival of Extremely Preterm Infants After Active Perinatal Care in Sweden
  • 2009
  • Ingår i: JAMA: the journal of the American Medical Association. - American Medical Association. - 1538-3598. ; 301:21, s. 2225-2233
  • Tidskriftsartikel (refereegranskat)abstract
    • Context Up-to-date information on infant survival after extremely preterm birth is needed for assessing perinatal care services, clinical guidelines, and parental counseling. Objective To determine the 1-year survival in all infants born before 27 gestational weeks in Sweden during 2004-2007. Design, Setting, and Patients Population-based prospective observational study of extremely preterm infants (707 live-born and 304 stillbirths) born to 887 mothers in 904 deliveries (102 multiple births) in all obstetric and neonatal units in Sweden from April 1, 2004, to March 31, 2007. Main Outcome Measures Infant survival to 365 days and survival without major neonatal morbidity (intraventricular hemorrhage grade > 2, retinopathy of prematurity stage > 2, periventricular leukomalacia, necrotizing enterocolitis, severe bronchopulmonary dysplasia). Associations between perinatal interventions and survival. Results The incidence of extreme prematurity was 3.3 per 1000 infants. Overall perinatal mortality was 45% (from 93% at 22 weeks to 24% at 26 weeks), with 30% stillbirths, including 6.5% intrapartum deaths. Of live-born infants, 91% were admitted to neonatal intensive care and 70% survived to 1 year of age (95% confidence interval [CI], 67%-73%). The Kaplan-Meier survival estimates for 22, 23, 24, 25, and 26 weeks were 9.8% (95% CI, 4%-23%), 53% ( 95% CI, 44%-63%), 67% (95% CI, 59%-75%), 82% (95% CI, 76%-87%), and 85% ( 95% CI, 81%-90%), respectively. Lower risk of infant death was associated with tocolytic treatment (adjusted for gestational age odds ratio [ OR], 0.43; 95% CI, 0.36-0.52), antenatal corticosteroids (OR, 0.44; 95% CI, 0.24-0.81), surfactant treatment within 2 hours after birth ( OR, 0.47; 95% CI, 0.32-0.71), and birth at a level III hospital (OR, 0.49; 95% CI, 0.32-0.75). Among 1-year survivors, 45% had no major neonatal morbidity. Conclusion During 2004 to 2007, 1-year survival of infants born alive at 22 to 26 weeks of gestation in Sweden was 70% and ranged from 9.8% at 22 weeks to 85% at 26 weeks.

  • Clinical characteristics and primary treatment of prostate cancer in Sweden between 1996 and 2005 - Data from the national prostate cancer register in Sweden
  • 2007
  • Ingår i: Scandinavian Journal of Urology and Nephrology1967-01-01+01:002013-01-01+01:00. - Taylor & Francis. - 0036-5599. ; 41:6, s. 456-477
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. The incidence of prostate cancer is rising rapidly in Sweden and there is a need to better understand the pattern of diagnosis, tumor characteristics and treatment. Material and methods. Between 1996 and 2005, all new cases of adenocarcinoma of the prostate gland were intended to be registered in the National Prostate Cancer Register (NPCR). This register contains information on diagnosing unit, date of diagnosis, cause of diagnosis, tumor grade, tumor stage according to the TNM classification in force, serum prostate-specific antigen (PSA) levels at diagnosis and primary treatment given within the first 6 months after diagnosis. Results. In total, 72 028 patients were registered, comprising > 97% of all pertinent incident cases of prostate cancer in the Swedish Cancer Register (SCR). During the study period there was a considerable decrease in median age at the time of diagnosis, a stage migration towards smaller tumors, a decrease in median serum PSA values at diagnosis, a decrease in the age-standardized incidence rate of men diagnosed with distant metastases or with a PSA level of > 100 ng/ml at diagnosis and an increase in the proportion of tumors with Gleason score <= 6. Relatively large geographical differences in the median age at diagnosis and the age-standardized incidence of cases with category T1c tumors were observed. Treatment with curative intent increased dramatically and treatment patterns varied according to geographical region. In men with localized tumors and a PSA level of <20 ng/ml at diagnosis, expectant treatment was more commonly used in those aged >= 75 years than in those aged <75 years. Also, the pattern of endocrine treatment varied in different parts of Sweden. Conclusions. All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer.

  • Weight increase in patients with dementia, and alteration in meal routines and meal environment after integrity promoting care.
  • 2007
  • Ingår i: Journal of Clinical Nursing. - 0962-1067. ; 16:5, s. 987-96
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: To follow weight changes in patients with moderate and severe dementia and analyse how these changes related to biological and psychological parameters after staff education and support in integrity promoting care. A further aim was to describe meal environment and routines relative to the intervention. BACKGROUND: Weight loss in patients with dementia and in particular Alzheimer’s disease (AD) is common. The etiology appears multifactorial with the meal environment and a decreased independence while eating among the factors. METHOD: Over a three-month intervention period, an integrity-promoting care training program was conducted with the staff of a long-term ward. AD patients, 18 from an intervention ward and 15 from a control ward were included and possible effects were evaluated. Weighing was conducted at the start and after completion of the intervention. Weight changes were analyzed in relation to psychological and biochemical parameters. In addition, the staff wrote diaries about e.g. changes made in the environment and in their work.RESULTS: The most prominent difference observed was weight increases in 13 of 18 patients compared to two of 15 patients in the control ward. No weight changes were related to the type of dementia. The individual weight changes correlated significant to changes in the intellectual functions. Relationships between weight change, increased motor function and increased appetite were non-significant. There was no significant relationship between weight changes and changes in biochemical parameters. According to the staff, increased contact with the patients and a more pleasant atmosphere resulted when the meal environment and routines were changed. RELEVANCE TO CLINICAL PRACTICE: Weight gain in patients with moderate and severe dementia was achieved by adjusting the meal environment to the individual’s needs. Staff education was profitable, as increased competence seemed to promote individually adapted feeding situations. Ensuring good meal situations need to be given high priority.

  • Psychosocial aspects of traumatic spinal cord injury with onset during adolescence: A qualitative study
  • 2007
  • Ingår i: JOURNAL OF SPINAL CORD MEDICINE. - 1079-0268. ; 30, s. S55-S64
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND/OBJECTIVE: Spinal cord injury (SCI) occurring during adolescence poses additional challenges because of the concurrent age-specific bio-psychosocial development. Full understanding of the psychosocial dimensions of rehabilitation requires exploration of the patient perspective. The objective of this study was to focus on psychosocial factors from the patient perspective in persons who had previously sustained a SCI during early and mid-adolescence (11-15 years of age). METHODS: Twenty-four of the 28 persons who had sustained a SCI in Sweden from 1985 to 1996 participated in the study. Semistructured interviews were made an average of 10 years after injury. Narratives were analyzed qualitatively according to content analysis. RESULTS: Parents and peers were found to have formed a crucial network. Parents frequently acted as advocates in interactions with health care providers, as supporters, and as containers of sorrow, frustration, and anger. Peers acted as promoters of activity and identity development. However, health care providers were perceived as not making sufficient use of this network. CONCLUSIONS: Rehabilitation professionals might be encouraged to increase their knowledge of adolescence medicine to better meet the specific needs and demands of persons in this age group. It is further suggested that parents and peers be considered important partners in the joint rehabilitation effort.

  • Antifouling activity of brominated cyclopeptides from the marine sponge Geodia barretti
  • 2004
  • Ingår i: Journal of Natural Products. - 0163-3864. ; 67:3, s. 368-372
  • Tidskriftsartikel (refereegranskat)abstract
    • In this work, we show the potent antifouling effects of two compounds, barettin (cyclo[(6-bromo-8-entryptophan)arginine]) (1), isolated as a Z/E mixture (87/13), and 8,9-dihydrobarettin (cyclo[(6-bromotryptophan)arginine]) (2), isolated from the marine sponge Geodia barretti. The compounds were isolated guided by their ability to inhibit the settlement of cyprid larvae of the barnacle Balanus improvisus, and their structures were determined by means of mass spectrometry, NMR, and quantitative amino acid analysis. The activities of these brominated diketopiperazine-like cyclic dipeptides are in the range of antifouling agents in use today, as shown by their EC50 values of 0.9 and 7.9 muM, respectively. However, contrary to today's antifouling agents, the effects of barettin and 8,9-dihydrobarettin are nontoxic and reversible. A small set of synthetic analogues, including L-arginine, L-tryptophan, 5-bromo-D,L-tryptophan, 6-bromo-D,L-tryptophan, and 6-fluoro-D,L-tryptophan, were tested for possible structure-activity relationships. None of these compounds showed any effect at a concentration of 10 muM. We hypothesize that the isolated compounds are part of the sponge's chemical defense to deter fouling organisms. This theory is supported by the fact that barettin is found in water exposed to living specimens of G. barretti in concentrations that completely inhibit barnacles from settling.

  • Factors that influence the use of ambulance in acute coronary syndrome.
  • 2008
  • Ingår i: American heart journal. - 1097-6744. ; 156:1, s. 170-6
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: National guidelines recommend activation of the emergency medical service by patients who have symptoms of acute coronary syndrome (ACS). In spite of this, only 50% to 60% of persons with myocardial infarction initiate care by using the emergency medical service. The aim of this study was to define factors influencing the use of ambulance in ACS. METHODS: The method used in this study was a national survey comprising intensive cardiac care units at 11 hospitals in Sweden; 1,939 patients with diagnosed ACS and symptom onset outside the hospital completed a questionnaire a few days after admission. RESULTS: Half of the patients went to the hospital by ambulance. Factors associated with ambulance use were knowledge of the importance of quickly seeking medical care and calling for an ambulance when having chest pain (odds ratio [OR] 3.61, 95% CI 2.43-5.45), abrupt onset of pain reaching maximum intensity within minutes (OR 2.08, 1.62-2.69), nausea or cold sweat (OR 2.02, 1.54-2.65), vertigo or near syncope (OR 1.63, 1.21-2.20), ST-elevation ACS (OR 1.58, 1.21-2.06), increasing age (per year) (OR 1.03, 1.02-1.04), previous history of heart failure (OR 2.48, 1.47-4.26), and distance to the hospital of &gt;5 km (OR 2.0, 1.55-2.59). Those who did not call for an ambulance thought self-transport would be faster or did not believe they were sick enough. CONCLUSIONS: Symptoms, patient characteristics, ACS characteristics, and perceptions and knowledge were all associated with ambulance use in ACS. The fact that knowledge increases ambulance use and the need for behavioral change pose a challenge for health-care professionals.

  • Novel biochemical markers of psychosocial stress in women.
  • 2009
  • Ingår i: PloS one. - 1932-6203. ; 4:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Prolonged psychosocial stress is a condition assessed through self-reports. Here we aimed to identify biochemical markers for screening and early intervention in women. METHODS: Plasma concentrations of interleukin (IL) 1-alpha, IL1-beta, IL-2, IL-4, IL-6, IL-8, IL-10, interferon-gamma (INF-gamma), tumor necrosis factor-alpha (TNF-alpha), monocyte chemotactic protein-1 (MCP-1), epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), thyroid stimulating hormone (TSH), total tri-iodothyronine (TT3), total thyroxine (TT4), prolactin, and testosterone were measured in: 195 women on long-term sick-leave for a stress-related affective disorder, 45 women at risk for professional burnout, and 84 healthy women. RESULTS: We found significantly increased levels of MCP-1, VEGF and EGF in women exposed to prolonged psychosocial stress. Statistical analysis indicates that they independently associate with a significant risk for being classified as ill. CONCLUSIONS: MCP-1, EGF, and VEGF are potential markers for screening and early intervention in women under prolonged psychosocial stress.

  • Steric influence on the excited-state lifetimes of ruthenium complexes with bipyridyl-alkanylene-pyridyl ligands.
  • 2008
  • Ingår i: Inorganic Chemistry. - ACS. - 0020-1669 .- 1520-510X. ; 47:9, s. 3540-3548
  • Tidskriftsartikel (refereegranskat)abstract
    • The structural effect on the metal-to-ligand charge transfer (MLCT) excited-state lifetime has been investigated in bis-tridentate Ru(II)-polypyridyl complexes based on the terpyridine-like ligands [6-(2,2'-bipyridyl)](2-pyridyl)methane (1) and 2-[6-(2,2'-bipyridyl)]-2-(2-pyridyl)propane (2). A homoleptic ([Ru(2)(2)](2+)) and a heteroleptic complex ([Ru(ttpy)(2)](2+)) based on the new ligand 2 have been prepared and their photophysical and structural properties studied experimentally and theoretically and compared to the results for the previously reported [Ru(1)(2)](2+). The excited-state lifetime of the homoleptic Ru-II complex with the isopropylene-bridged ligand 2 was found to be 50 times shorter than that of the corresponding homoleptic Ru-II complex of ligand 1, containing a methylene bridge. A comparison of the ground-state geometries of the two homoleptic complexes shows that steric interactions involving the isopropylene bridges make the coordination to the central Ru-II ion less octahedral in [Ru(2)(2)](2+) than in [Ru(1)(2))(2+). Calculations indicate that the structural differences in these complexes influence their ligand field splittings as well as the relative stabilities of the triplet metal-to-ligand charge transfer ((MLCT)-M-3) and metal-centered ((MC)-M-3) excited states. The large difference in measured excited-state lifetimes for the two homoleptic Ru-II complexes is attributed to a strong influence of steric interactions on the ligand field strength, which in turn affects the activation barriers for thermal conversion from (MLCT)-M-3 states to short-lived (MC)-M-3 states.
